C cking Member Aug 10, 2023 #1 Got a used motor, know nothing about it. Has a cam with HM3 engraved on it. Anyone know what cam that likely is? Looks like stock lift cam but the cam lobes look pretty flat like it may have extra duration.

C cking Member Aug 11, 2023 #3 That was my guess as well. Just wasnt sure what the "3" stood for. Maybe the 3 is the advance or retard degrees of the cam...

I have /had a couple of dovers cams . They pretty much followed the progression of cam design. Now advanced or retarded couldn't say.
